To all whom it may concern:

Be it known that I, Ions Ssttsns llANcnorr, of Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented a certain new and useiul Improvement in Keyboard Mechanism for Perforating and other-Machines; and I do.hereby dech'e the-following to be a full. clear, and- (not description of the same, reference being bad to the accompanying drawings, forming a part of this s mcification, and to the figures and letters of reference marked thereon.

This invention relates to a keyboard mechanism especially designed for use in connection with record.

strip perftmsting machines. but alike applicable to other varieties of keyboard machines and it has for its principal object to simplify and improve the mechanism whereby the action of the punches and other devices are controlled from the finger keys.

In a prior application (Serial No. 179,048, filed Oct. 29, 1993) of which this is a division is shown, described and claimed a keyboard mechanism coIwisting-cssentially of a plurality of keys, two series of valves materially less in number than the keys, and means whereby the .keys may be selectively coupled with the valves of the two series irrespective of the location of the key.

The pmsent-invention consists in a modified construction in which the keybank is provided with a plurality of series of keys, each of the latter coupled with a valvesof. one series through an actuating bar q'optlmon to that series of keys, .while the individual each series tire coupled with the valves of the series through actuating bars controlling said lutl ns'mul series of valves, the arrangement bei'ng suchfthat each valve of one series is controlled by-s 36 sipgle-series of'keys and the valves of the other series 'esepQutL-ly controlled by the individuals comprising said 'series of keys.

It consists in the emf1loyment of two series of detecting bars disposed in cross wise relation to each 40 other below thtfkeys. each actuating bar controlling ,45 l is an end elevation of the keybank. Fig. 2 is a partinl' top plan view, the top and finger lleys being removed. 3 is a perspective'view of a portion of the transmission s'ysteni, showing the manner oi connecting each key to the actuators of thtwo series of valves. l'is aside elevation of the ,valve act'ust ing bar for series of valves.

Like numerals designate corresponding parts in the seven] figures. The invention is designed for use in connection with the perforating machine 0! Patent No. 664,115, as a 6i substitute for the ks'ybapk and control valves thereof, togovern thesdmissionofpreasuretothescricaolsupply pipes leading to the punch cylinders, and it is shown as applied to the improved arrangemcntof punch cylinders included in an application Serial No. 179.048, 60 filed Oct. 29, 1903, of which latter this is a division. In the commercial machines of this type there are two hundred and twenty five keys, thirty one punches and thirty two punch bars and cylinders. 0f the punch' bars, fourteen represent successive degrees oLsdjust- 66 mcnt, another fourteen represent corresponding adjustments in a direction transverse to the first, and, in addition, designate degrees of adjustment 0! the mold, while of the remaining four, one is blank. one represents the space type, and the remaining twoths justi- 70 fication designating signals. 01 the last nsmcdjonr, two,-the blank and space-operate upon the messuring devices making sixteen in all, andjg purposea of description this g'rouporseries' 6} sixteen punch bars -will' be designated the space-value group or series'in ll that they all operate upon and affect the movements of the'line measuringmechanism.

In the priou'nschins each punch bar ws'i provided with a motor.(in the form of a piston and cylindg), which, with one exception i. c., the justification-space punch bar, was controlled by all ghakoys in a or line, accordingly as it hslonfod to the space-value or non-space valtwgroup, and each key was equipped with-a valy'a coiitrolling a motor of each group, corrosponding with the column and line in which mid key was located, with thre'xfcsption of the last Orbottom row and right hand column; ssch of which controlled but s..-slngle.motor. This arrangement nocsdtatod the employment of not less than two hundred and twenty live valves to operate the thirty punches, and I0 as the keys composing each row or column controlled but a single space-value punch bar and motor, the. available area for the distribution of characters on the keyboard'was circumscribed, and, because of the multiplicity of valves, the waste of pressure, due to leakage,

aswell as the cost of construction, I adjustment ind maintenance was excessive. As the present inve it n relates only to the means for controlling'the punch oar motors it will suflice for present purposes tonemarkthat g each punch bar motor is connected by a pipe 1 tt :|o n fl IN a ssrissof inlet ports 2-, located within a common 'valfl chamber or trunk 3; the latter outside of and beyond munieating al through pipe 8, with the pressure supply. An exlmm port 5 is located inproxirnhy l oaeh aupplypon 2, and each lot of pom; is controller! by a slide- 1 5 valve 8 or 9; There are an many of timer: slide valves 1 u than a punch bar motors, one for each, to perform the work oi tho two hundred incl twenl y live valves of ()"liguul; thus the valves 6 located inllre Cilmsziw: m

The keyri,'proieralrly manger! in series in prmdlel columns, are in the form of bellcrnnk levenr 10, one arm l0 [unlinked vii-h a. rlesignuiting button or finger piece 11 sud the other vlillr rln extension or cross-bar 12, the bum bridging or extending over a. series of parallel permutgtion bura lil.
